Nemo Xo Steel 308Win 16

The NEMO Arms XO Steel .308 Winchester 16-inch precision tactical rifle is a purpose-built carbine that splits the difference between close-quarters maneuverability and long-range accuracy. At 34.25 inches overall length and just 8.2 pounds, it's compact enough for tight spaces yet rigid enough to deliver sub-MOA groups when paired with quality optics and ammunition. This is serious hardware for hunters, tactical shooters, and precision rifle enthusiasts who refuse to compromise on either mobility or performance.

Every component reflects NEMO's no-nonsense design philosophy. The 16-inch Bartlein barrel (1:8 twist, 416 stainless) is precisely machined in-house and pairs with a patented recoil-reduction bolt carrier—an industry-first feature that meaningfully softens felt recoil without sacrificing reliability. The dual-chamber compact muzzle brake is tuned to run either suppressed or unsuppressed, giving you flexibility on the job. The gas block allows quick switching between those two modes, and the mid-length gas system stays severe-duty stainless throughout.

The trigger is a Geissele Super Dynamic Enhanced (SD-E) two-stage unit (2.3 lbs first stage, 1.2 lbs second stage) that breaks clean and predictably. The receiver set is billet 7075-T6 aluminum with full ambidextrous controls, a 15-inch M-LOK rail, and NEMO's anti-tilt "Carrier Cradle" receiver extension. High-pressure bolt, tool-steel extractor, titanium takedown pins, and nickel-boron coatings throughout mean this rifle is built to run hard. Comes with a MAGPUL CTR stock, MIAD grip, and a 20-round P-MAG.

Whether you're hunting in tight timber, running drills at distance, or building a versatile precision platform, the XO 16 delivers the accuracy and handling to match your skill.
